A sphere has radius 50mm and mass 1kg falling vertically through air of density 1.2kg/my attains a steady velocity of 11m/so. if the above equation is applied to it's fall what is the value of k?

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
